摘要

描述了DRAGON SLAYER的文件管理系统，DRAGON SLAYER是一个分布式操作系统，在异构局域网中提供透明的资源共享，控制完全分散。用户可以使用其授权的任何系统文件，而不必考虑文件所在计算机的个人特征或用户和文件的物理位置。此外，还可以对文件进行动态分片，并且可以动态地复制和重新定位这些碎片。当所有文件操作在整个文件或特定片段上透明地工作时，副本保持相互一致。提出了支持这些文件系统操作的DRAGON SLAYER资源管理。除了在文件访问可靠性和灵活性方面具有明显的优势外，作者还通过仿真结果证明了该文件系统与具有非碎片文件的传统分布式文件系统相比具有优越的性能。

Distributed management of replicated and partitioned files under DRAGON SLAYER

The authors describe the file management system of DRAGON SLAYER, a distributed operating system which provides transparent resource sharing in a heterogeneous local area network with completely decentralized control. Users are able to use any of the system files for which they have authorization, without regard to the individual characteristics of the computers on which the files reside or the physical locations of the users and files. In addition, files can be dynamically fragmented, and the fragments can be replicated and relocated dynamically. Copies are kept mutually consistent while all file operations work either transparently on the whole file or on specific fragments. The DRAGON SLAYER resource management supporting these file system operations is presented. Beyond the obvious advantages of file access reliability and flexibility, the authors present simulation results proving the superior performance of this file system as compared with conventional distributed file systems with non-fragmented files.<>
